Description

Shower head

Technical Field

The utility model belongs to the technical field of the shower head, specifically a shower head, the shower that specially adapted utilized the venturi effect uses.

Background

The shower head is a device commonly used for bathing, and has the main function of dispersing water flow, so that a bather can enjoy good bathing and showering effects. In order to conveniently control the shower heads, switch valves are arranged on some shower heads, and the switch valves need to be operated by two hands to adjust the opening or closing states of the switch valves, so that the switch valves are inconvenient to adjust, and a part of the switch valves can be used for rapidly realizing the switching of the water opening and closing by one hand. The shower head capable of switching the water flow on and off by one hand is generally in a pressing type, the water flow is communicated when the shower head is pressed down, and the water flow is automatically reset through a spring to realize the disconnection of the water flow when the shower head is stopped being pressed down.

The shower head as shown in figure 1 comprises a body, a water flow channel is arranged in the body, a valve core channel is arranged vertically and penetrates through the water flow channel, a valve core is arranged in the valve core channel in a sliding mode, an elastic part for resetting is generally arranged between the bottom of the valve core channel and the valve core, a valve hole which is in the same direction as the water flow channel is further arranged on the valve core, cylindrical sealing parts for leak-proof sealing and water passing are arranged on two sides of the valve core in the water flow channel, the outer diameter of each cylindrical sealing part is slightly larger than the valve hole and is attached to the side face of the valve core, when the valve core is pressed down, the cylindrical sealing parts are communicated with the valve hole, the water flow channel of the shower head; when the valve core is loosened, the cylindrical sealing element is staggered with the valve hole, the water flow channel of the shower head is disconnected at the moment, and the shower head stops water outlet.

In the prior art, there is a shower using venturi effect, such as a self-priming portable shower disclosed in CN205031138U, which is based on the principle that tap water flows in a venturi tube to automatically suck hot water and cold water to mix and spray out from a shower head, thereby achieving warm water bathing effect. In order to increase the capacity of absorbing hot water, the shower takes the process factors (too small to be processed), the blockage problem and the bathing comfort problem (too small water yield) into consideration, the diameter of the minimum end of the water inlet of the Venturi tube is about 1.5-1.75mm, when the diameter of the minimum end of the water inlet of the Venturi tube is within the range of 1.5-1.75mm, the caliber of a water flow channel in the shower head is required to be about 7mm, and the water yield can be close to the water yield of a common shower head for bathing. Otherwise, the resistance of the water flow channel is too large, the water absorption capacity of the Venturi tube is insufficient, on one hand, the water yield is too small, and on the other hand, the water outlet temperature cannot meet the requirement. The current commercially available shower head capable of switching water flow on and off by one hand is generally about 5mm in diameter of a water flow pipeline as shown in fig. 1, and the main reason is that a cylindrical sealing element is required to have certain elasticity so as to ensure the joint sealing with a valve core, and if the diameter of a valve hole is overlarge, the cylindrical sealing element is easily partially embedded into the valve hole in the sliding process of the valve core, and the situation of damage and water leakage is easily caused after the valve core is circulated for several times, so that the structure shown in fig. 1 cannot be applied to the shower head with the water flow channel caliber requirement of about 7 mm.
